      The study examined the effect of caffeine supplementation on match activities and development of fatigue during a football match. In a randomised, double-blind cross-over design, two experimental football games separated by 7 days were organised between the junior teams of two professional football clubs (17.6 ± 1.1 years (±s), 71.7 ± 6.9 kg, 13.9% ± 5.0% body fat). The players ingested either a ...

      The present study evaluated the effect of a smaller, lighter ball on kicking speed and technical- tactical and physical match performance in high-level adult female footballers. In the laboratory test setting, the peak ball velocity was 6 % higher with the new ball (NB) than the standard ball (SB) (26.5 ± 0.5 vs. 25.1 ± 0.5 m · s − 1, p < 0.05). However, during match-play, no differences ...
